NCT00334113
The overarching objective of this study is to develop an innovative strategy to address the problems of obesity and diabetes by promoting exercise adoption. An automated telephone intervention will be developed that can be used to enhance exercise adoption over a twelve month period in a population of overweight or obese veterans with Type 2 diabetes.
NCT00784511
North American blacks tend to have low blood levels of vitamin D because pigmentation blocks vitamin D production in the skin. They also have higher rates of developing type 2 diabetes and higher rates of complications from the disease compared with whites. Although there is compelling evidence that adequate vitamin D may reduce the risk for type 2 diabetes in whites, recent evidence from a national survey demonstrated an association of vitamin D with diabetes in whites but not in blacks. However, the central hypothesis of this study is that providing enough supplemental vitamin D to blacks (raising their blood levels higher than that of most participants in the survey) will improve blood measures related to diabetes risk. The proposed study is a 12-week randomized, double-blind, placebo-controlled experiment designed to examine the effect of vitamin D supplementation (100 μg/d ) on insulin secretion, insulin sensitivity and glucose control in pre-diabetic black men and women aged 40 and older.
NCT01786408
This study will involve an investigational device, the Seventh Sense Biosystems TAP20-C. The TAP20-C device collects small amounts of blood from the forearm which can then be used for blood testing. The study will also involve collecting blood by fingerstick which is a common way of collecting blood. The SAFE-T-FILL Capillary Blood Collection system and the Terumo Capiject 1.5 mm Blade Safety Lancet will be used for this. The study will compare the concentrations of glucose, hemoglobin, and HbA1C in blood samples collected with the two different blood collection methods. Additional information will be collected about how the TAP20-C device performs.
